About Java ES 5 Update 1 Application Server

Release 5U1 Application Server is a maintenance release that fixes bugs in Release 5 Application Server. Release 5 Application Server (Application Server 8.2) was a maintenance release with respect to Release 4 (Application Server 8.1 UR2), including only selected bug fixes. Release 5U1 Application Server is functionally the same as Release 4.

Application Server Upgrade Roadmap

The following table shows the supported Application Server upgrade paths to Java ES 5 Update 1.

Table 9–1 Upgrade Paths to Java ES 5 Update 1: Sun Java System Application Server Enterprise Edition 8.2 Patch2

Java ES Release	Application Server Release	General Approach	Reconfiguration Required
Release 5	Sun Java System Application Server Enterprise Edition 8.2	Maintenance Upgrade. Apply patches.	None
Release 4		Direct upgrade of Application Server from Release 4 to Release 5U1 is not supported. This upgrade path is supported by first upgrading Release 4 Application Server to Release 5 Application Server and then upgrading Release 5 to Release 5U1. The information about upgrading Release 4 to Release 5 is documented in Sun Java ES 5 Upgrade Guide for Microsoft Windows.

Application Server Data

The following table shows the type of data that could be affected by an upgrade of Application Server software.

Table 9–2 Application Server Data Usage

Type of Data	Location	Usage
Environment variables	ApplicationServer-base\config\asenv.bat	Global variables
Configuration data	ApplicationServer-base\domains\domainName\config	Configuration of Application Server instances
Deployment data	ApplicationServer-base\domains\domainName\applications	Configuration of J2EE container for specific J2EE components and applications

Application Server Compatibility Issues

Java ES 5 Update 1 Application Server does not introduce any interface changes with respect to Java ES 5.

Application Server Dependencies

Application Server dependencies on other Java ES components can affect the procedure for upgrading and reconfiguring Application Server software. Changes in Application Server interfaces or functions, for example, could require upgraded versions of components upon which Application Server depends. The need to upgrade such components depends upon the specific upgrade path.

Application Server has dependencies on the following Java ES components:

• Shared components. Application Server has dependencies on specific Java ES shared components, as listed in Table 1–8.

• Message Queue. Application Server depends on Message Queue to provide J2EE Java Message Service-compliant asynchronous messaging support.

• HADB. Application Server depends on High Availability Database (HADB) for high availability storage of HTTP session. HADB is designed to support up to 99.999% service and data availability with load balancing, failover, and state recovery.

• NSS. Application Server depends on Network Security Service (NSS) for managing security.

• Web Container (optional). Application Server depends upon web container services for its optional load balancing plug-in. This support can be provided by Java ES Web Server.

Upgrading Application Server from Java ES 5

This section includes information about upgrading Application Server from Java ES 5 to Java ES 5 Update 1 . The section covers the following topics:

• Introduction

• Release 5 Web Server Upgrade

Introduction

When upgrading Release 5 Application Server to Release 5U1, consider the following aspects of the upgrade process:

• General Upgrade Approach. The upgrade is achieved by patching Release 5 Application Server.

• Upgrade Dependencies. Application Server has dependencies on a number of Java ES shared components (see Table 1–8).

• Backward Compatibility. Release 5UI Application Server is backwardly compatible with the Release 5 version.

Release 5 Application Server Upgrade

This section describes how to perform an upgrade of Application Server from Java ES Release 5 to Release 5U1. This section covers the following topics:

• Pre-Upgrade Tasks

• Upgrading Release 5 Application Server

• Verifying the Upgrade

• Post-Upgrade Tasks

• Rolling Back the Upgrade

Pre-Upgrade Tasks

Before you upgrade Application Server, perform the tasks described below.

• Verify Current Version Information

• Upgrade Application Server Dependencies

• Backing Up Application Server Data

Verify Current Version Information

Verify the current version of Application Server before you upgrade.

To Verify Current Version Information

1. Type the following command:

   WebServer-base\asadmin version --verbose

   This command returns the Application Server version information.

   Release 5U1

   Sun Java Enterprise System Application Server Enterprise Edition 8.2

   Release 5

   Sun Java Enterprise System Application Server Enterprise Edition 8.2

Upgrade Application Server Dependencies

It is generally recommended that all Java ES components on a computer system (and in a computing environment) be upgraded to Release 5U1. Release 5U1 Application Server has hard upgrade dependencies on Message Queue and on the NSS shared component, so these should be upgraded before upgrading Application Server. Upgrading Application Server to Release 5U1 requires that Windows Installer patch (126910–02) is already applied.

Backing Up Application Server Data

The Application Server upgrade from Release 5 to Release 5U1 does not modify the Release 5 configuration data. You do not need to back up current data.

Upgrading Release 5 Application Server

This section discusses considerations that impact the upgrade procedure for Application Server, followed by a description of the procedure itself.

Upgrade Considerations

The upgrade of Application Server software to Java ES Release 5U1 takes into account the following considerations:

• In a deployment architecture in which there are multiple instances of Application Server running on a single computer (all corresponding to the same installed Application Server image), you only have to upgrade the Application Server image once.

• In a maintenance upgrade, you do not have to migrate schema, configuration, security or user data.

• The Release 5U1 Application Server upgrade patches for Windows are shown in the following table:

Table 9–3 Patches to Upgrade Application Server on Windows

Description	Patch ID [Patch revision numbers are the minimum required for upgrade to Release 5U1. If newer revisions become available, use the newer ones instead of those shown in the table.]
Application Server core	124684–04
Application Server Localization	The localized patch files are delivered within the core patch.

Upgrade Procedure

The procedure documented below applies to Application Server instances residing locally on the computer where the upgrade is taking place.

To Upgrade Application Server to Java ES 5 Update 1

1. Log in as administrator.

2. Shut down all Application Server instances.

   1. Stop the Domain Administration Server.

      ApplicationServer-base\bin\asadmin.bat stop-domain domainName

   2. Stop the Node Agent.

      ApplicationServer-base\bin\asadmin.bat stop-node-agent nodeagentName

3. Make sure you have upgraded any Java ES components upon which Application Server has hard upgrade dependencies (see Upgrade Web Server Dependencies.

4. Obtain the required Application Server Release 5U1 upgrade patches, based on Table 9–3.

   To obtain the patch, see Accessing Java ES Patches. Patches can be downloaded to \workingDirectory.

5. Install the patch.

   Installation is generally performed by running patch-id.exe, however, be sure to consult the README.patch-id file in the patch directory for installation instructions.

   ---

   Note –

   If you are prompted to restart the system, select No. Wait till the patch installation process is completed and then restart and re-login as the same user to complete the patch installation.

   ---

6. Verify the patch log file.

   The log file is found at: %TEMP%\SUNJAVAES_<patch-id>.log

7. Verify the patch installation with the utility ListJavaESPatches.exe.

   Run ListJavaESPatches.exe and check that the output includes the patch id of the patch that you have installed in Step 5. For more information, see Identifying Installed Java ES Patches.

8. Start the Release 5U1 Application Server domains and node-agents of all the instances.

   ApplicationServer-base\bin\asadmin.bat start-domain --user admin-user-ID/ --passwordfile passwordFileName domain-name

   ApplicationServer-base\bin\asadmin.bat start-node-agent --port admin-Port --user/ admin-user-ID --password admin-password node-agent--name

Verifying the Upgrade

You can verify successful upgrade of Application Server by starting the Application Server instance as follows:

AppServer-base\bin\asadmin version --verbose

The messages that indicate the Java ES release version are:

Release 5U1
